Be it known that I, TnEononE'P. BROWN, a citizen of the United States, residingnt Worcester, in the county of Worcester and" State of Massachusetts, have invented a new" and useful Reversing and Rewinding Mechof which the following is a specification- This invention relates to thatclass of automatic musical instruments which are controlled by rolls or strips of perforated paper.

The especial object of this invention is to provide the reversing le-ver of an instrument of this class with simple and direct means for connecting the motor to .wind the musicsheet over the tracke1' -board in one direction or to connectthe motor to rewind the musicsheet at a higher speed, to throw off the con- Specificaticn 01 Letters Patent. Applicatiof filed Septeuiber 2 5, 1905c Serial Not 279,926.

Turning with the shaft 29 v wh ch when shifted in one direction will turn nection of the motor and its governor during rewinding, and to cut off the air tension from. the pneumatic action during rewinding.

To these ends this invention consists of the reversinglever and the connections controlled thereby, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a front view, partly broken away, of sufficient parts of an automatic musical instru- 1 merit to illustrate the application of this in ingroll R and vention thereto; and Fig. 2 is a perspective view of the reversing-lever and connections operated therefrom In that class of automatic musical instrie ments to which this invention relates whenever a piece of music is played automatically the music-sheet has to be drawn over the tracker-board in one direction, and after the piece is played the music-cheet has to be rewound upon the music-roll. The reu'iuding may be done at ahigher speed than the speed of the paper during playmg, and it is desir-- able that the motor should he relieved from f the resistance of its governor during rewin mg.

It is also desirable when a pneumatic wimling-motor is used, that the air tension should be cut off from the playing device during rewinding; lit will be seen that the i'evei-sing--ltwei' of an automatic musical instrument has to be l operated very frequently when the instru- 1 went is in use. 1

The especial object of my present invena to arrange the conuu'tions controlled the reversing-lever in s ch simple and direct Way that the rcvcrsiugd-vvcr will-work l governor, as this subject-matter I in prior application for patent,

are so direct andpositive-that they will not readily become brokeii or require attention.

Referring to the accompanying drawings fora detail description of an apparatus constructed according to this invention, T designates the tracker-board','Which cooperates with, the music-sheet. site sides of the tracker-board T are the music-rollM and the winding-rollR. The motor P may be of the ordinary Wind-motor typeand is provided with the usual crankshaft 27. Secured at one end of the crankshaft 27 is a sprocket-wheel connected bya chain 28 to a sprocketswheel on the shaft 29.

a pinion meshingwith the gear of the Windwhen shifted in the opposite direction will connect with the sprocketwheel having a chain 31 for turning the music-roll at higher speed w slieet is being *rewound. Fastened at the other. end of the crank-shaft 27 is a sprocketwheel connected by a chain 32 to a clutchpiece 33, which can be moved out of or into engagement to drive the centrifugal governor G. The speed of the centrifugal governor G is regulated hy the adjustment of the stop lever 34, tlte raising of said lever permitting tle governor to turn more rapidly and the music to be played faster, or the time can be slowed down by lowering said lever.

It is to be understood that in this application for patent .1 do not claim the combination of the wind-motor with the centrifugal is claimed 227,802, filed by me October 10, 1904.

To cut oil air tension from the pneumatic action while still permitting the motor to operate during the rewinding of the musicsheet, i provide a cut-off valve for the pneumatic action, which cut-off valve is controlled hy a valve-stem 35.

)uring rewindmg it is desirable that the motor should be relieved of all restraint of the governor, and I have provided connections from the rewinding-lever arranged so that the rewinding-lever not only changes the direction in which the music-sheet is board, but also throws the governor out of gear with the motor and cuts off air tension from the pneuinatic action.

As herein illustrated, the reversing-lever is a clutch 30,'

In the v particular construction illustrated it will be seen that the proportions ofthe gearing'are such that the music-sheet will be rewound' at "comparatively high speed and that'the connections from the reversing-lever are arranged-in: simple and direct way, 'so that they can be operated With'littl'e resist ment orrepairs, I am aware that changes maybe made in the construction Ihave herein shown and described; but
